EPF8820AQC160-4

The EPF8820AQC160-4 is a member of the FLEX 8000 programmable logic device family, offered in a 160-pin BQFP surface-mount package. The device implements logic using compact logic elements (LEs) and delivers approximately 8,000 usable gates with 672 logic elements, making it suitable for mid-density programmable logic designs.

Designed for commercial applications, this device targets bus interfaces, coprocessor functions and high-speed control tasks that benefit from in-system reconfigurability, predictable interconnect, and a rich register count. It operates from a 4.75 V to 5.25 V supply and supports a 0 °C to 70 °C ambient range.

Key Features

• Logic Capacity  672 logic elements providing approximately 8,000 usable gates for implementing mid-density logic functions.
• I/O and Package  Up to 120 user I/O pins in a 160-pin BQFP surface-mount package (supplier package listed as 160-PQFP, 28 × 28 mm footprint).
• Voltage Supply  Operates from 4.75 V to 5.25 V, matching legacy 5 V system environments.
• Commercial Temperature Grade  Rated for 0 °C to 70 °C operation and designated commercial grade for general-purpose embedded applications.
• On-chip Memory  Total RAM Bits: 0 (no embedded SRAM reported for this part).
• In-system Reconfigurability  Supports in-circuit reconfigurability via external configuration devices or an intelligent controller, enabling field updates and design iteration.
• Fast, Predictable Interconnect  Family-level FastTrack interconnect and dedicated carry and cascade chains provide structured routing and arithmetic support for high‑fan‑in logic and fast adders/counters.
• Output Control & Low Power  Programmable output slew-rate control to reduce switching noise, and typical standby current specified at low microampere levels in the family data.
• Surface-Mount Mounting  Surface-mount device simplifies automated assembly for production quantities.
• RoHS Compliant  Device is RoHS compliant for lead-free assembly processes.

Typical Applications

• Bus Interfaces  Integration of multiple bus widths and TTL logic, leveraging the device's I/O count and predictable interconnect for reliable data-path implementation.
• Coprocessor and Glue Logic  Use as custom coprocessor logic or glue between system components where mid-density logic and many registers are required.
• High-Speed Controllers  Implementation of high-speed control and timing-critical logic benefiting from dedicated carry/cascade chains and compact LEs.
• System Integration  TTL integration and system-level functions in commercial embedded products where 5 V operation and high I/O counts are needed.

Unique Advantages

• Balanced Mid-Density Resource Set  672 logic elements and ~8,000 usable gates give you a balance of logic capacity without moving to larger, more complex devices.
• High I/O Count in a Compact Package  120 user I/Os in a 160-pin surface-mount package reduce PCB routing complexity for multi-bus designs.
• In-System Flexibility  In-circuit reconfigurability allows field updates and iterative development without board replacement.
• Deterministic Routing  Family FastTrack interconnect and dedicated arithmetic chains enable predictable timing for arithmetic and high-fan-in functions.
• 5 V System Compatibility  4.75 V–5.25 V supply range aligns with legacy 5 V digital systems and TTL interfaces.
• Compliance and Assembly-Friendly  Commercial-grade rating, surface-mount package, and RoHS compliance streamline manufacturing and regulatory alignment.
